Answer:
Fred has saved $115 while Wilma had saved $230
Step-by-step explanation:
Let the amount saved by Fred be F while the amount saved by Wilma be W
Together, they have saved $345
Mathematically;
F + W = 345 •••••••(i)
We are also told that Wilma has have twice as much money as Fred;
Hence; W = 2F ••••••••(ii)
To get the amount of money they both have, we need to solve the equations simultaneously
Substitute ii into i
F + 2F = 345
3F = 345
F = 345/3
F = 115
But W = 2F
W = 2 * 115
W = 230
He set the factored expressions equal to each other. instead of setting them equal to zero
<h3>What are quadratic equations?</h3>
The name Quadratic comes from "quad" meaning square because the variable gets squared (like x2). It is also called an "Equation of Degree 2
The given solution of the quadratic equation in the question is
His work is shown below.
Here is where we use the zero product property
x+3 = 0 x+1 =0 We do not set them equal to each other
Hence He set the factored expressions equal to each other. instead of setting them equal to zero

Answer:
Terms: 4f and 8, coefficient: 4, and constant: 8
Step-by-step explanation:
Terms in an equation are every single part (not including the +, -, etc.)
Coefficients are the numbers in front of a variable (letter)
Constants are numbers that do <em>not</em> have a letter attached to them
